Abstract - This research paper deals the study on Impact on Water Quality of Krishna River after Amalgamation of Godavari River Water via pattiseema. Water Quality Index (WQI) is a single no which tells that water is in what state by using all the parameters. It is very useful to all the people to know the status of water quality very easily. As the pure water is not sufficient to all so amalgamation of rivers has been going from few decades in all over the world. The Krishna River has unique nature of water quality due to its subsurface. In the present study, the water quality of Krishna River with the addition of Godavari water has been studied. The 2 liter water samples are collected by Grab Sampling process at a distance of 50meters from river Catchment at five different places of Krishna & Godavari Rivers and they are mixed with proper mix proportions, and then analyzed in the laboratory using APHA standard procedures. With the help of analytical results, the WQI was estimated using weighted average method with the use of IS10500:2012 standards and those are compared with standard WQI values. Initially the WQI of Krishna River has Good Quality Status. The result of the work states that the average Krishna’s water quality has fall under Poor water quality region after amalgamation of Godavari due its nature. Key Words: (Surface water, Krishna River, Godavari River, Water Quality Parameters and Water Quality Index.)

1. INTRODUCTION
Water is one of the gifts from nature and also basic needs to survival on the earth. The 90% of water can recycle and used for daily purposes. The formation of water is a hydrological cycle process. The sources of water are surface and ground water. Basically the water is pure condition but due to mixing of many particles quality has been changed. The water is important for any type of industries. The 50% wastes from industries are directly released to rivers and seas. Due to insufficient rainfall, to balance the demand and supply of water the Government of India has taken an action to inter link the major rivers (like Krishna-Godavari). The parameter of one river differs from another. So, by that the water quality also changes. Hence it is needed to compare the water quality of Krishna River before and after amalgamation of Godavari River. Here we used a predefined tool to find the Water Quality Index status. WQI is one of the most effective and simplified tool to communicate information on overall quality status of water to the concerned user community and policy makers. The Krishna & Godavari Rivers are the biggest rivers in terms of water capacity & river catchment area in India. These are long, widen and originate at western lands of Maharashtra at elevation of 1300mts above sea level and ends at Bay of Bengal. Krishna-Godavari basin, it is a major source of irrigation for Maharashtra, Karnataka, Telangana and Andhra Pradesh. To satisfy all needs so many dams and barrages are constructed on rivers. So due to these heavy hydraulic structures the capacity of the catchment areas of these structures are rapidly decreasing. Hence government of AP has taken a decision of amalgamation of Godavari River’s flood water with Krishna water through polavaram right bank canal by pattiseema lift with national water way ISO 9001:2008 Certified Journal
